IMPROVED SCAI-Folin The Schedule referred to in these Letters Patent and making` part of the same `iBeit known that I, GEORGE W, WnLLs,'-of Lawton, in the county of Van Buren, and State of Michigan,

vhave invented anew and useful`lmprovement in Paiutersand Builders Scabld; and I do declare that the following is a true and accurate description thereof, reference being hail to the accompanying drawings, and to the'v letters of reference marked thereon, and being a' part of this specilication.

Figure l is a perspective view of my invention.

Figure 2 is aseotion of one of the braces. Like letters indicate like parts in each figure.

'The nature of this invention relates to the const-ruction of a scaffold for the use of painters and builders, and consists in the ladjustable supports, by means of Iwhich the desired height of the' scaiold may be deterinined, as hereinafter more fully set forth.

. B represents a brackethaving a pair of guide-braces, b, secured to the outer end-.of its shelf and to the'lower en'd of its standard.

Onftbe shelf is a pair ci' stationary hooks, a, with which engages a pair of eye-bolts, c, projecting from either end of a section of plat-form, A, which is held p in place by dropping a pin, ll, int-o the shelf of the bracket in front ofthe eye-bolt.

The scaffold thus formed is supported against the Y To all whom it may concern .f

' wall by inserting between thebraces bof each bracket a prop or brace, C, with its lower end on the ground.

To elevate theseaiold additional braces, C', are employed, and are jointed to the lower ends of the first series in the tbllowingmanner:

Each end of the braces is provided on the rear side with one leaf of a strap-hinge, e, which are joined together by a hinge-pin, f. Y

On the upper fr'out end ofthe lower brace is hinged a latch, g, having a harpoorr head which engages with a notch cut iu the lower end of the upper brace, and is held in place by a collar or sleeve, h, slipped over it. As the platforms are hinged to the brackets, each bracket may be elevated the length of a section of brace without interfering with the rest, and the process repeated until the desired elevation of `scalold is attained.

fWhat I-elaim as my invention, and desire to secure by Letters Patent, is-

, In portable scatfolds, the latch g, the strap hinge e,

the pin fand the collar h.`incornbiuatiou with the braces C and C', notched as described, when constructed and operating as and for the purpose set forth.
